IMPROVEMENT lN LAMP-CAPS AND SHADE-HOLDERS.

Specification forming part of Letters Patent No. 159,208, dated January26, 1875; application liled December 19, 1874.

To all whom it may concern.-

Be it known that I, WILLIAM R. PARK, of Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented a certain new anduseful Lamp-Gap and Shade- Holder; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it pertains to make anduse it, reference being had to the accompanying drawings, which formpart of this specitication, in which- Figure 1 is aplan of myimprovementapplied to a lamp-bowl; Fig. 2, a section showing the wedge-shaped armfor shade-supporter; and Fig. 3, a section showing the same withthreadand-screw attachment.

The object of my invention is to provide a metallic attachment for glasslamps, which will subserve the following purposes: First, as a radiator,to conduct the heat from the burner into the surrounding atmosphere, soas to avoid heating the lamp-bowl and fluid contained therein; second,as a base for the arms or supporters of a shade-holder; and, thirdly, asan ornamental appendage for a glass lamp.

1n the accompanying drawing, which illustrates my invention, A is ametallic ring or disk of any desired form or configuration, beingindependent of any particular design or shape. This ring may be made ofbrass and polished, or of cast-iron and bronzed or painted in one orvarious colors. It has a central opening, a, for the passage of thecollar of the lamp bowl or burner. From the edge of this opening rises avertical flange or annular shoulder, B. This flange B is designed totightly encircle the lamp-collar C, so as to keep the ring or disk Afirmly and securely in position. It serves also as a base or pedestalfor the attachment of arms D D D, which form supports for a shade. Thesearms may be secured in any suitable way, as by screwing their ends intoholes I) b tapped in the collar B, or by making said ends wedge-shaped,and forcing them in between the flange B and collar of the lamp, thislatter method serving to fasten the ring A more firmly upon the lamp.

The device I have just described may be applied to any glass lamp bymerely slipping it on, requiring no riveting or other means of securing.It thus furnishes a cheap and simple means of ornamenting glass lamps soas to present a rich and elegant appearance, and at the same time servesto conduct away and radiate the heat generated in the burner. It alsoprovides a ready and efficient pedestal for the shade-holder arms atmuch less expense than other devices hitherto usually employed for thesame purpose.

What I claim as my invention is- As a new article of manufacture, thecastmetal lampcap consisting of the plate A, adaptedto rest upon thebowl and the collar B, to embrace the neck of the lamp, substantially asshown and described.

In testimony that I claim the foregoing I have hereunto set my hand this16th day of December, 1874.

WILLIAM It. PARK.
